ReviewEffectiveness of melatonin treatment on circadian rhythm disturbances in dementia. Are there implications for delirium? A systematic review.
Circadian rhythm disturbances, like sundowning, are seen in dementia. Because the circadian rhythm is regulated by the biological clock, melatonin might be effective in the treatment of these disturbances. We systematically studied the effect of melatonin treatment in patients with dementia. In addition, we elaborate on the possible effects one might expect of melatonin treatment in patients with delirium, since dementia and delirium are strongly related. Moreover, some evidence exists that sundowning in patients with dementia and the alterations in the sleep/wake cycle, seen in patients with delirium both originate from circadian rhythm disturbances. ⋯ Sundowning/agitated behaviour improves with melatonin treatment in patients with dementia. There are several arguments that sundowning in patients with dementia and the alterations in the sleep/wake cycle in patients with delirium have a common background, namely a disturbance of the circadian rhythm. This suggests that melatonin treatment could also have the same positive effects in patients with delirium.

ReviewSuicide in later life: public health and practitioner perspectives.
Suicide in later life is a public health concern. Given the need for practical guidance and policy implementation, this paper aims to provide a critical interpretive synthesis approach to prioritize the likely relevance of publications and the contribution that they make to understanding of the problem. ⋯ For lack of sufficient evidence from intervention trials that are specific to older people, practitioners need to extrapolate from studies of younger adults and be aware of risk factors for suicide in later life. Public health approaches combined with practitioners' experiences of older people at risk may help minimize the risks of suicide in later life. These are fruitful areas for collaborative practice development, service initiatives, evaluation, and research.

Broad spectrum assessment of psychopathology and adaptive functioning with the Older Adult Behavior Checklist: a validation and diagnostic discrimination study.
Self-administered by spouses and other collateral informants, the nationally normed Older Adult Behavior Checklist (OABCL) provides standardized data on diverse aspects of older adult psychopathology and adaptive functioning. We tested the validity of the Older Adult Behavior Checklist (OABCL) scale scores in terms of associations with diagnoses of dementia of the Alzheimer's type (DAT) and mood disorders (MD) and with nine measures of psychopathology, cognitive performance, and adaptive functioning. ⋯ Multiple OABCL scales had medium to large associations with diverse indices of functioning based on other kinds of data. The nationally normed OABCL provides new ways to integrate informant and self-report data to improve assessment of older adults. Specifically, the OABCL can provide discrimination between those who qualify for diagnoses of DAT versus MD versus neither diagnosis.

Subtle deficits of attention after surgery: quantifying indicators of sub syndrome delirium.
To determine whether attentional impairments are reliable neuropsychological markers of sub syndrome delirium. ⋯ The distinction between people with sub syndrome delirium and no delirium is difficult to quantify but computerized measures of attention might provide a sensitive indicator. Sub syndrome delirium is an observable marker of a clinical abnormality that should be exploited to improve care management for vulnerable patients.
